<description><p>A <seeerl marker="wxGraphicsPath"><c>wxGraphicsPath</c></seeerl> is a native representation of a geometric path. The contents are specific and private to the respective renderer. Instances are reference counted and can therefore be assigned as usual. The only way to get a valid instance is by using <seemfa marker="wxGraphicsContext#createPath/1"><c>wxGraphicsContext:createPath/1</c></seemfa> or <seemfa marker="wxGraphicsRenderer#createPath/1"><c>wxGraphicsRenderer:createPath/1</c></seemfa>.
</p>
<p>This class is derived (and can use functions) from:

<desc><p>Adds an arc of a circle.
</p><p>The circle is defined by the coordinates of its centre (<c>x</c>, <c>y</c>) or <c>c</c> and its radius <c>r</c>. The arc goes from the starting angle <c>startAngle</c> to <c>endAngle</c> either clockwise or counter-clockwise depending on the value of <c>clockwise</c> argument.
</p><p>The angles are measured in radians but, contrary to the usual mathematical convention, are always <c>clockwise</c> from the horizontal axis.
</p><p>If for clockwise arc <c>endAngle</c> is less than <c>startAngle</c> it will be progressively increased by 2*pi until it is greater than <c>startAngle</c>. If for counter-clockwise arc <c>endAngle</c> is greater than <c>startAngle</c> it will be progressively decreased by 2*pi until it is less than <c>startAngle</c>.
</p><p>If there is a current point set, an initial line segment will be added to the path to connect the current point to the beginning of the arc.
